Abstract: L'invention concerne la production de chaînes chimères codantes pour des protéines induisant dans le récepteur des effets dirigés contre les virus. Ces protéines stimulent la production d'une réponse humorale sérotypique spécifique et une protection contre l'infection aux virus de la dengue, permettant ainsi d'éviter les effets d'amplification virale sérotypique non spécifiques qui causent des hémorragies et des complications cliniques décrites dans ce type de pathologie. Ces chaînes d'acides nucléiques sont constituées par la combinaison spécifique de fragments appartenant au gène d'une protéine mutante à activité déshydrogénase de N. meningitidis et de fragments qui codent pour une région de la protéine E de l'enveloppe des virus de la dengue. Par ailleurs, ces chaînes d'acides nucléiques, lorsqu'elles sont insérées dans un vecteur d'expression, donnent lieu à des protéines chimères présentant des caractéristiques spécifiques. Les molécules chimères selon l'invention trouvent leur application dans l'industrie pharmaceutique, plus précisément dans l'élaboration de préparations vaccinales et de diagnostics à haute spécificité sérotypique destinés à des êtres humains.

Abstract: A method for activating chemical reactions using non-thermal capillary discharge plasma (NT-CDP) unit or a non-thermal slot discharge plasma (NT-SP D) unit (collectively referred to as "NT-CDP/SDP"). The NT-CDP/SDP unit include s a first electrode disposed between two dielectric layers (8 and 9), wherein the first electrode and dielectric layers having at least one opening (e.g., capillary or a slot) defined therethrough. A dielectric sleeve (3) inserted into the opening, and at least one second electrode (2) (e.g., in the shape of a pin, ring, metal wire, or tapered metal blade) is disposed in fluid communication with an associated opening.

Filed: 2002-08-31
Abstract: A mod of combustion and a multi-component reactor to accomplish this mode of combustion are disclosed which produces fullerenes and fullerenic material b y combustion. This mode consists of de-coupling an oxidation region of a flame from a post-flame region, thus giving greater control over operating parameters, such as equivalence ratio, temperature, and pressure ; allows conditions of the operating parameters of the combustion reaction to be attained which would not be easily attained by conventional methods ; and offers the ability to more easily stabilize the combustion reactions to allo w for higher throughputs of fuel and oxidant. Several embodiments of a primary zone of a multi-component reactor are also disclosed. Said primary zone serv es as the oxidation region, operates on the principle of providing recycle to t he reacting combustion mixture, and which may be operated as approximately a we ll- mixed reactor. A secondary zone is also disclosed which provides further residence time for reaction and the ability to control operating parameters, operates on the principle of minimizing recycle of the reacting combustion mixture. The secondary zone may be operated as approximately a plug-flow reactor. The primary and secondary zones may be operated in conjunction or either one alone.

Title: Method and system for gasifying biomass
Inventor: BOERRIGTER HAROLD
IPC: C10K1/18
Filed: 2002-08-22
Abstract: Method and device for cleaning synthesis gas obtained during gasification of biomass. The synthesis gas is passed through a saturation device and an absorption device, both of which are fed with oil. In this way the synthesis gas is scrubbed with oil and tar is substantially removed therefrom. The tar-containing oil which is released in this process is subjected to a cleaning step, as a result of which oil with a high percentage of tar and oil with a relatively low percentage of tar are formed. The first oil can be returned to the gasification, and the remaining oil can be reused.

Title: Extension of link aggregation protocols over the network and a switching node therefor
Inventor: MARK BARRY DING KEN
IPC: H04L69/40
Filed: 2001-06-15
Abstract: An extension of a Link Aggregation Protocol (LAP) over the network allows current Ethernet point-to-point LAPs to operate across a Metropolitan Area Network (MAN). A maximum disjoint path algorithm allows selection of a plurality of alternative end-to-end physical routes between two data terminals. These physical routes share a minimum number of nodes and physical links. End-to-end logical links are then formed by a plurality of successive physical links between nodes containing protocol compatible devices, the physical links being selected based on their physical characteristics such as bandwidth and delay. Multiple logical links can be provisioned, without dedicating, between any two data terminals over the network. The logical links provide the virtual point-to- point links that the edge LAP devices require. The extension of LAP/s over the network provides increased availability because a network failure can now be propagated to the edge of the network to allow the edge LAP devices to quickly react to the failure.

Abstract: A medical diagnostic method and instrumentation system for analyzing noncovalently bonded agglomerated biological particles is described. The method and system comprises: a method of preparation for the biological particles; an electrospray generator; an alpha particle radiation source; a differential mobility analyzer; a particle counter; and data acquisition and analysis means. The medical device is useful for the assessment of human diseases, such as cardiac disease risk and hyperlipidemia, by rapid quantitative analysis of lipoprotein fraction densities. Initially, purification procedures are described to reduce an initial blood sample to an analytical input to the instrument. The measured sizes from the analytical sample are correlated with densities, resulting in a spectrum of lipoprotein densities. The lipoprotein density distribution can then be used to characterize cardiac and other lipid-related health risks.

Title: Implant, and method and system for producing such an implant
Inventor: HALL JAN
IPC: A61L27/30
Filed: 2002-12-18
Abstract: In a method and system for producing an implant, the latter is designed with one or more surfaces extending in the longitudinal direction of the implant.  Two or three production stages can be used. In one stage, either a topography with a long wave pattern is produced by means of cutting work, or laser bombardment or further cutting work is used to produce a topography with an intermediate-length wave pattern. In addition, an oxidation process or shot-peening or etching is used to produce an outer layer. When using two of said production stages, said cutting work or said laser bombardment or further cutting work is followed by the oxidation process or the shot-peening or etching method. When using all three production stages, cutting work is followed by laser bombardment, or further cutting work, which in turn is followed for example by the oxidation process. The invention also relates to an implant which is produced using the method and is identified, ordered and produced using the system. The invention permits effective treatment of different implant situations.

An apparatus according to the instant invention includes a high field asymmetric waveform ion mobility spectrometer (FAIMS) having an analyzer region defined by a space between an inner electrode (32) and an outer electrode (34). In particular, the outer electrode includes an ion inlet (38) for introducing ions into a first portion of the analyzer region and an ion outlet (56) for extracting ions from a second portion of the analyzer region.  The FAIMS is characterized in that a gas-directing conduit (48) is provided through at least a portion of the inner electrode. In particular, the gas-directing conduit includes an opening at a first end thereof for supporting fluid communication between the gas-directing conduit and the first portion of the analyzer region. The gas-directing conduit is adapted at a second end thereof opposite the first end for supporting fluid communication between a gas source and the gas-directing conduit. The opening is orientated relative to the ion inlet such that gas provided through the gas-directing conduit flows partially outwardly from the analyzer region through the ion inlet, so as to desolvate the ions produced at an ionization source (42, 45) as they are introduced into the analyzer region.
